"Stop trying to be a Jack-of-all-trades and be a master of one thing. Whether it’s writing an email, kicking a ball around with your kids, driving through the city or simply being alone and meditating. For those ten minutes you’re doing something – or for whatever period of time it takes – do it with 100-per-cent focus."
